THE OYSTER AND THE FLYING FISH

An oyster was a'travelling
Along the ocean road;
He'd been some time preparing,
And now he'd left the fold.

He was sick of being oysterized,
And he wanted to explode,

                                       To explode.

He saw a pretty flying fish
And said if I could have one wish
I'd change into a flying fish,
And then I would be happy. 

The flying fish came down to see
Just who had made this plea;
And seeing the poor oyster,
Said this cannot be.

An oyster has to stay inside,
And a flying fish must flee

All the time. 

As the oyster turned to go away,
The flying fish was heard to say,
"If I could find a place to stay,
I know I would be happy, yes I would."
Ooh la, ooh la, ooh la, ooh la,
Ooh la la la.
